I guess my original point was that you'll find both system and market apps that hold wake locks. (BTW your web browser should be able to display that packages.xml file if you want to have a look in it)

Well, I don't know for sure, but that image you attached sure seems to implicate Maps.

The thing is - and it's one of the things that sort of sucks about android - is that it is difficult to filter broadcast receivers. So, apps can spring back to life even if you've manually killed them if a separate app generates a matching broadcast that the former has registered for.

Some market apps are greedy in this regard - they register for all sorts of broadcasts so an appearance is maintained that they open quickly - on the off chance that a user will be sharing data between the app currently in use and that (other market) app.

In prior versions of Android, lots of apps - both system and market apps - would register as broadcast receivers for certain events produced by the stock email app. If you browsed the inbox, no problem... but as soon as you open an individual email, a whole slew of apps would get launched in the background.

Anyway - and this is a hypothesis - even if Maps is preventing sleep by holding wake locks, it could be a different app that is causing it to spring to life - or even a rather obscure startup cycle that depends on both market apps and/or system apps before Maps finally gets restarted.

If you manually kill off Maps and then shut the screen off, and then come back some time later and find Maps running again, you should be able to observe the event that restarts Maps in the logcat output.

good luck

Whoop - sorry. I was using BTEP (Better Terminal Emulator Pro) which comes with it's own private busybox (not installed in /system)

You could also install a busybox flash, but I would recommend you use one that doesn't touch /system/bin or /system/xbin. (I think at least on of the market versions might refer to this as a "safe install") I'm not familiar with them, so I can't recommend a particular version.
[Nexus 7 General] Nate2:
Right you are, sir!

I stopped Maps at 19:36, and exactly 1 hour later at 20:36, it re-started itself:

02-23 19:36:57.740 1121 1133 I ActivityManager: Killing proc 5340:com.google.android.apps.maps/10070: kill background

...

02-23 20:36:22.210 1121 1152 I ActivityManager: Start proc com.google.android.apps.maps for service com.google.android.apps.maps/com.google.googlenav.prefetch.android.PrefetcherService: pid=6033 uid=10070 gids={3003, 1015}

I can't find what app (if any) might have caused that. pid=6033 looks all Maps-related, not 3rd party.
[Nexus 7 General] bftb0:
Not sure myself either.

That logcat message looks a little different than an intent sent from a different app.

I suppose you have some more digging to do.

Sorry I'm not more help - my N7 rarely leaves the house, so if it's not in use it is on the charger. The consequence of that is that I have no idea whether it fails to sleep or not; I certainly wouldn't know from looking at the battery charge state/history anyway.

Don't know how helpful this is, but if the N7 does go into deep sleep, you will see messages in the kernel log (dmesg or /proc/kmsg) about entering the LP0 state.

Tedious to correlate those messages with logcat though - I think those messages are reported in seconds since boot rather than GMT or local time ... and worse yet that timestamp seem to get screwed up by LP0 sleep. (LP0 is a very deep sleep - the SoC is very nearly off completely - even the memory controller is turned off)

good luck

2 minutes of wakelocks over 23 hours isn't much. are there kernel wakelocks? the alarms don't seem to be too much either..
[Nexus 7 General] bftb0:
I conclude your OS is fine and your battery is bad in the CT702. Perhaps the full cell voltage decreases with age, but what I notice in the above is that it is saying your 98% capacity was only at 3889 mV.

Granted, its not a N7, but I would expect devices using the same battery chemistry to exhibit the same charge voltage range. (Maybe there is more about Li-Ion/Polymer batteries that I need to learn about, too).

The battery in my unit - admittedly only about 8 weeks old - swings between about 3660-4170mv.

That is only a swing of 500 mV for a full discharge cycle - but you are showing less than half of that at a "full charge." I suppose that the full-scale (charged) voltage of the battery pack might decline as it ages, but that seems pretty extreme. Moreover, if you believe the voltage decline statistic, I conclude that whatever made this report thinks that your 100% voltage swing is only 97 mV

( 21% @ 1.9%/hr => 11.1 hrs; 5.2%/hr @ 11.1 hrs => 57%; 56 mV/0.57 = 97 mV)

Those Maps wakelocks are indeed leading the pack - but only in the 2% or so percent of the time that the device is not sleeping. Also - note that 1.9%/hour statistic - when the device is only on about 1.9% of the hour: if it is correct, it would imply that the tablet would fully discharge itself in a single hour if it was on continuously. That certainly can't be the way the tablet is designed to work.

BTW, what app produced this output?

Looks like maps is the main culprit for my N7 as well I let it run over night while I was sleeping.

[Nexus 7 General] bftb0:
@Nate2

I'm not sure I would be too worried about 0.1%/hr, even if the tablet never sleeps! That said, those services (Updater and PowerManager) seem more likely to be the trouble than Maps.

@Triscuit

The second image indicates Maps only held wake locks for a few minutes. Seems highly doubtful that you lost 8% of your battery charge in 5 minutes.
[Nexus 7 General] Nate2:
Yes, in about 15 minutes off the charger, this CT702 loses 5% battery:

Level lost [%]: 5 Bat.: 5% (100% to 95%) [20.0%/h]

Voltage lost [mV]: 368 (4145-3777) [1472.0%/h]
[Nexus 7 General] Nate2:
Managed to control the battery drain on my Nexus 7 (see pics).

I've installed Auto Airplane Mode (auto shut off data), Greenify (stop some apps) and Autorun Manager (to disable SystemUpdateService$Receiver to reject OTA updates to my Android 4.1.2).

Probably don't need all the above to prevent the tablet from waking up and draining the battery like it used to, so I might see if I can get by without Greenify first.

None of the battery monitoring apps I use are responsible for the battery drain (someone suggested they might be).
[Nexus 7 General] player911:
Sounds like one of your market apps.

Unless you are using the same kernel and rom by the same dev.

Facebook has always been a big battery drainer. Google Now also seems to grab a lot of battery, as so does maps on occasion. N7 sleeps like a champ. Never had issues with getting days of not using it.

Hi Guys! In my Audi cabriolet there was no GPS navigator sistem, there are a lot of other optional but this no.

The Audi dealer asked me about 1.600 euro for install the original Audi Navigator.... A poor device with 6.5" display and no touch....

Prehistoric object!!

So in december 2011 i bought a GT8.9 3G, and after some months of planning and labor i permanently installed the tab in the car.

First:

View attachment 1748669

After:

View attachment 1748670

View attachment 1748671

View attachment 1748672

This is the features of the Carmobileproject:

1) FM Radio (web radio with Tune In app)

2) MP3 music player

3) GPS navigator (Sygic, Tom Tom, maps, ecc)

4) Phone (gsm and voip calls)

5) Player films

6) Internet and mail

7) Autodiagnosis real time with bluetooth EOBD interface

8) Satellite antitheft with realtime GPS Tracker

I planned and build an electronic circuit interface, which detects the theft and send to the tab a signal. So automatically start a call, a sms at my number and start the GPS tracking. In this way i can follow the thieves and recover the car.

9) Possibility of send a command to the car (by sms) so as activate some gadget in the car (for example turn off the engine so as interrupt the thieves sprint).

Actually in the tab run an AOKP rom (Milestone 6 android 4.0.4), but soon i will install AOKP 4.2.2. Thank you to addem1234, a guy of XDA which have build the last version of AOKP for our tab! A fantastic and super customizable ROM.

[Galaxy Tab 8.9 General] zmagas1:
I have a question, do you somehow added external storage or you satisfied with 16 GB internal? How?
[Galaxy Tab 8.9 General] carmobileproject:
well, i use the 16GB internal for apps, mp3, and navigator maps. For the other (films, ecc.) i use OTG feature with pen drive 32GB.

I must modify the 30 pin dock connection for working the OTG and the charge from USB at the same time. In fact, if you connected a OTG cable in our tablet you can not powered it. I need to have also the power in the tab so as i can detect when the car is on or off.
[Galaxy Tab 8.9 General] zmagas1:
That is great, can you provide instructions on how you manage to work OTG and charging at same time.?
[Galaxy Tab 8.9 General] carmobileproject:
well, it's no simple..... In any way, you have to build a custom cable with pin out of standard.

I have bought an original samsumg cable, open the 30 pin connector, extract the micro-contact and repositioned in the right pin. Than sold the wires. Look at this pictures:

[Galaxy Tab 8.9 General] Maboroshy:
Here is my installation with stock dock. The tab is removable.
[Galaxy Tab 8.9 General] zmagas1:
More details please. How do you attached it, was is the model of car?
[Galaxy Tab 8.9 General] Maboroshy:
The car is BMW X1. It has useful "glove box" in place of stock car infotainment I don't have. I've only made power and aux cording to the box. For now the dock is holding by itself with the plugs pushing the box top ant the rear and the front edge pushing rubbered flour. The tab and the rubber hold it intact. So all I need is to push the docked tab into box, it stands quite firm by itself. Without the tab the box can be easily closed with the dock in.

After a while the tab started to disconnect on some major bumps (which we have plenty here). I'm reconsidering an attachment to resolve this. However there be no major modifications, maybe some extra struts on the tab to push down, cause for now only dock is pushed down, not the tab.

The soft part based on Tasker works like a charm. Only video registration running on background causes minor issues, which may be related to the 7300’s low internal memory performance.
[Galaxy Tab 8.9 General] i96danma:
Thanks for showcasing your builds - one simple and one incredibly ambitious!

It seems like there's an entire computer (VIC-20 style :)) at the back of the tab, is that to control the actuator? And is the actuator for controling on/off? Also, was it "simple" or "impossible" to relocate the buttons and AC panels? And what about controlling the radio stuff; amplifier is still stock, I presume?

Lots of questions but this is just too cool! I've seen a few car builds but nothing in this scale.
[Galaxy Tab 8.9 General] carmobileproject:
Hi! The hardware at the back of the tab drive the actuator and much more!! (power the tab, manage the USB OTG, manage antithieft interface, adapt the level of the output, ecc. ecc.)

It's impossible to relocate the power button!!!

The amplifier is an Audison 4x80W

For control the final volume i used a double logaritmic potentiometer with push button.

The push button drive the actuator

https://android.googlesource.com/platform/bootable/recovery/
[Nexus 7 Q&A, Help & Troubleshooting] bftb0:
Absent information to the contrary, it is possible that you can continue to use the 4.13 bootloader with 4.2.2 kernels.

Bootloaders are proprietary however - so there is nobody here that can tell you for sure just how important the changes from 4.13 -> 4.18 are. Simply put, the only people who know what those changes are are a few engineers at Asus.

I look at it this way - flashing a boot loader is the single most perilous flashing operation that can be performed. So - for Asus/Google to decide "let's put our entire customer base at risk by having them flash the boot loader as part of an OTA install" - well, that indicates that Asus/Google thought the bug fixes or capability changes in the new version were important - not trivial.

---------- Post added at 07:02 AM ---------- Previous post was at 07:00 AM ----------

That is the recovery, not the bootloader. The bootloader is proprietary code.
[Nexus 7 Q&A, Help & Troubleshooting] Fuctifino:
This is why I get confused about different Android devices and custom ROMs.

I assume with the Samsung Galaxy series of phones that the bootloader is built into the ROM at base level as it's something we never have to with them.

As you stated it's the 'most perilous flashing operation that can be performed' so allowing that as an OTA is even more of a concern, slight corruption during the download and it'll be a right pain to sort out.
[Nexus 7 Q&A, Help & Troubleshooting] bftb0:
In my experience it is sort of unusual for an OTA to include a bootloader update, but the amount of risk involved depends on the details of how the operation is performed.

In the case of a pure-stock OTA, the downloaded package is crypto-signed and verified by the stock recovery. Not even a single bit can be off as a result, so there is absolutely zero risk of a "bad download". Using a custom recovery though, all bets are off - it is my impression is that neither CWM or TWRP can perform jar-signing checks correctly, and it is unclear whether they can actually verify the alternate Android-centric zip signing (turned off by default anyway)

The way the bootloader flash is performed by the N7 OTA is that the bootloader image is dropped into the USP partition. It would appear (because it is no longer in there after some time) that the pre-existing boot loader checks this partition for the presence of a replacement bootloader, and flashes it into it's final destination. I have to imagine that this process also protected by some kind of crypto/checksum - otherwise that behavior would be an automated "brick-maker".

So the OTA delivery method for bootloader install is pretty darn safe - but this is probably NOT TRUE for flashing with fastboot. The latter method (fastboot) may have absolutely zero protections against flashing garbage or truncated files to the device, resulting in a brick at the next hardware reset.

If you want to use fastboot for bootloader flashing, use a laptop to avoid the tiny risk of a power failure during the flashing operation, and TRIPLE-CHECK the MD5 signature of the image file you are planning on sending.

It also goes without saying that if you have been experiencing occasional data transfer failures when using fastboot, you should not be using fast boot for flashing the bootloader.

If you want to do it the safest way possible, revert to pure stock 4.2.1, make sure your battery is well charged, and take the OTA.
